I have a mix of art for my main sona, my badge commission collection is mostly traditional with only a few digital, while my bigger pieces tend to be digital because its easier to acquire but out of the big purchased commissions the most I have spent on a single commission was on a traditional piece from hibbary and it was totally worth it (it was a full color painting which was scanned in and is in my gallery)

most people like the look of digital art online because it looks cleaner in the format but at conventions most like traditional from what I saw mew.

Probably because digital art is easier to receive, show off online, and store. Traditional art is wonderful, but it's not so great if you don't have the space or money for framing and displaying it.
